DOUGH-WORKING APPARATUS. g,

Specification of Letters Patent. 7 Patented June 4, 1912, Applicationfiled January 20, 1912. Serial No. 672,326.

To all whom it ma concern:

Be it'known that I, DAVID J. HANNA, a citizen of the United States ofAmerica, and residing at Fishkill on-the-Hudson, in the county ofDutchess and State of New York,

have invented a certain new and Improved Dough-Working Apparatus, ofwhich the following is a specification.

My invention relates to apparatus for working dough and particularly toan improved apparatus, designed to work and shape dough, the object ofmy invention being to provide an improved apparatus which will have animproved working action upon the dough and which may be so employed asto expedite the preparation of the dough for the baking tins.

In the accompanying drawings, Figure 1 is a side elevation of anapparatus in which my invention is embodied in one form; Fig. 2 is alongitudinal section through portion of an apparatus of modified form;Figs. 3 and 4 are diagrammatic sections through further modified forms;and Figs aandfi, f are cross sections through working channels,

of different forms.

The present apparatus in the form illus trated in Fig. 1, comprises asupporting frame 10 carrying a longitudinally-curved,

inverted trough-like member or form .11 mounted in stationary positionon the top of the frame. Rollers 12 and 13 at the opposite ends of theframe support a traveling compression apron 14 which passes beneaththetrough juxtaposed to the lower face thereof. From the roller 13, thisbelt passes over the driving roller 15, yielding tensioning roller .16journaled on the end of a lever 17 which is pivoted on the frameand-carries an adjustable counter-weight 18 by which the tension of thebelt may be varied. If. desired, the rollers 13 and 15 may be gearedtogether, as diagrammatically illustrated by the dotted lines 19, 20,while bevel gearing 21, 22 may be arranged on the shaft of the roller 15and the spindle 23 respectively toy drive the roller 24 on the latter.In cross-section the trough 11 appears as a flat-bottomed channelsection, as illustrated in Fig. 5.

Assuming the dough to have passed through the usual dividing or scalingma chine, and to have been proofed sufliciently after balling, it isdischarged from the conveyer belt 25 upon the apron 14 -and carried onthe latter beneath the stationary form.

During its passage beneath the latter it is rolled over and over by theapron and is gradually transformed into cylindrical shape, its lengthbeing limited by the width of the trough. I In this-shape it isdischarged upon the 'conveyer belt 26 passing over roller 24, by whichit is carried to the sheeting rolls of the usual molding machine, to bet ere prepared for baking pans.

*T e action of the yielding, flexible compresion, belt 14 is far lessharshthan the usu l rigid rolls and the dough comes from the pparatuscomparatively unaffected and reqi iringmuch less proofing than is ordi-7o nariy the case. The action of this flexible aprn is in fact sogentle, especially if the aprnis of soft'material and the face of the his covered with like material, that the balling, proofing and moldingoperatio s may be eliminated and in their stead the chunks of doughdischarged from the divi, ermay be passed directly through the pr esntapparatus from which they emerge fed and ready for the baking pans.isoperation however, it is advisable e arrangement of apron and form besuch a'sgto secure a longer working act-ion upo thekdough. Thus for anapparatus of the type shown in Fig. 1, the trough or form 26 is muchIlengthened and flattened so that the dough chunks are worked by theapron 14 three or four times as much as are the balls in Fig. 1.

In Fig. 3 form 27 is shaped on a curve and the rollers 12 and 13 are soarranged that the apron l4 hugs the form for the major portion of itslength. In this arrangement the frictional advance of the materialthrough the apparatus is assisted by, gravity.

In Fig. 4 the driving members are reversed. Here the form takes theshape of a channeled wheel 28 driven from any suitable source, While thecompression apron 29, though yieldable, does not travel, being securedat one end to the support 30 and passed over portion of the wheel 28 andidler pulleys 31 32 to the tensioning weight 33 at its other end.

Any suitable. cross-section may be given the trough; according to theshape which it is desired to impart to the final loaf. Thus in Fig. 6 Ihave shown the trough 34 concaved. This will have the effect ofproducing a loaf of greater diameter at the middle than at the end.

interposed dough, said apron being unfup Various modifications of theapparatus will readily suggest themselves and I do not limit myself tothe details of structure illustrated.

I claim as my invention 1. In apparatus of the character described,

a form and a flexible, yielding compression a trough-shaped form and aflexible, yielding compression apron lying in said trough, incombination with means for moving said elements with relation to eachother to work interposed dough, said apron being unsupported during theworking portion of its travel, substantially as described. l

3. In apparatus of the character descr bed, a trough-like form havingits web shaped to the desired contour of the finisheddoiugh, a flexible,yielding compression apron lying in such trough and means for movingisaid elements with relation to each other to work ported during theworking portion 0 its travel, substantially as described. '1

4. In apparatusof the character descr'bed, a form and a flexible,yielding compred apron juxtaposed thereto, in combination with means formoving said elemeints with relation to each other to work interposeddough, at least one of said elements having its juxtaposed face of softmaterial, said apron being unsupported during the working port-ion ofits travel, substantially as described. i" .7

5. In apparatus of the character described, a form and a flexible,yielding compression apron juxtaposed thereto, in combination with meansfor moving said elements with relation to each other to' iv'orkinterposed dough, both of said elements having their juxtaposed faces ofsoft material, said apron being unsupported duringt'he workingpo-rtionof its travel, substantially as described. 6. In apparatus of thecharacter described, a form, a flexible apron, yieldable means tendingconstantly to hold said apron in contact with said form and means formov ing said apron and form with relation to each other toworkinterposed dough, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.
